Revolutionizing EV Powertrains: YASA’s Bid for Sustainable Motor Technology
In a significant stride towards sustainable electric vehicle (EV) manufacturing, YASA, a prominent developer of electric motors, has announced a groundbreaking initiative. The company will spearhead the development of two innovative axial flux motor designs, engineered to either minimize or completely eradicate the use of rare-earth magnets. This ambitious undertaking, named Project Resilience, is bolstered by a substantial grant from the UK government’s DRIVE35 Demonstrate competition, with all development work slated for YASA’s state-of-the-art engineering and development facilities across the United Kingdom.
This strategic move underscores a growing industry imperative to mitigate dependencies on geopolitically sensitive and environmentally impactful rare-earth materials. By focusing on next-generation axial flux motor technology, YASA aims not only to enhance the performance and efficiency of future electric vehicles but also to establish more robust and sustainable supply chains for the burgeoning EV sector.
Addressing the Rare-Earth Challenge in EV Motor Development
The reliance on rare-earth elements, particularly heavy rare earths, for high-performance permanent magnets presents a multifaceted challenge for the global automotive industry. These materials are crucial for withstanding the intense temperatures and demanding operational conditions inherent in advanced electric motors. However, their supply chains are predominantly concentrated in specific geographical regions, rendering manufacturers vulnerable to export restrictions, significant price volatility, and potential disruptions.
Beyond geopolitical concerns, the extraction and processing of heavy rare earths are often fraught with environmental issues. These processes can be highly carbon-intensive and have considerable ecological footprints, pushing the industry to seek more sustainable alternatives. YASA’s Project Resilience directly addresses these critical issues, aiming to de-risk the supply chain and promote greener manufacturing practices for axial flux motor technology.
A Dual Pathway to Rare-Earth Independence
YASA’s approach under Project Resilience is bifurcated, pursuing two distinct yet complementary development routes. The first pathway focuses on designing heavy-rare-earth-free permanent-magnet solutions. These are specifically tailored for high-performance battery-electric vehicles (BEVs) and hybrid vehicles, where maintaining power density without increasing motor mass or package size is paramount.
Simultaneously, the company will embark on developing fully rare-earth-free axial flux technology. This second route is designed to cater to a broader spectrum of vehicle applications, where different balances of performance, cost, and manufacturing requirements are essential. This dual strategy allows YASA to offer a versatile portfolio of sustainable EV motor solutions, meeting the diverse demands of the automotive market.
Modular Architecture: Driving Innovation and Efficiency
A cornerstone of YASA’s strategy for these new motor designs is the utilization of a common stator technology. This foundational component will serve as the basis for both development pathways, fostering the potential for a highly flexible and modular motor architecture. In this innovative setup, various rotor technologies can be seamlessly integrated and selected according to the specific needs of each vehicle program.
The shared stator technology offers substantial advantages, enabling YASA to leverage its existing engineering, design, development, and manufacturing expertise across both pathways. This synergy not only streamlines the development process but also significantly broadens the range of applications that YASA’s cutting-edge axial flux technology can effectively address. The modularity promises greater efficiency in production and adaptability in design, crucial for the rapidly evolving EV landscape.
The UK Government’s Strategic Investment in Automotive R&D
Project Resilience is a direct beneficiary of the DRIVE35 program, an initiative meticulously delivered by the Department for Business, Innovation, Science and Trade, in close collaboration with the Advanced Propulsion Centre UK (APC) and Innovate UK. This program is an integral component of the UK government’s overarching Advanced Manufacturing Sector Plan.
Under this comprehensive plan, a substantial commitment of £4 billion in grant funding has been allocated, stretching through to 2035. This significant investment is earmarked for automotive research and development, scale-up initiatives, and transformative projects, all aimed at cementing the UK’s position as a global leader in advanced manufacturing and electric vehicle innovation. Such governmental backing is vital for fostering a robust domestic supply chain and attracting further private sector investment in sustainable technologies.
Project Resilience stands as one of ten Demonstrate projects announced concurrently, collectively sharing £9 million in government funding. The Advanced Propulsion Centre (APC) highlights that the combined investment from both government and industry across these ten projects surpasses £18 million. A key requirement for projects funded through the Demonstrate program is the ability to build a product or process demonstrator within a stringent 12-month timeframe, underscoring the focus on rapid, tangible results. While the precise size of YASA’s individual award for Project Resilience was not publicly disclosed, its inclusion in such a competitive program underscores the project’s strategic importance and potential impact.
Expert Commentary and Future Outlook
Highlighting the strategic vision behind this initiative, Tom Hillman, YASA’s Head of Motor Simulation, articulated the company’s pragmatic approach. “Project Resilience is about creating credible alternatives without losing sight of what vehicle manufacturers need from an electric motor,” Hillman stated. He further elaborated on the nuanced requirements of the market: “Different applications require different balances of performance, efficiency, packaging, cost and production volume, which is why we are developing two complementary technology routes rather than pursuing a single universal solution.”
This outlook reinforces YASA’s commitment to providing tailored, high-value solutions that resonate with the diverse demands of the electric vehicle market. The success of Project Resilience in developing viable rare-earth-free axial flux motor technology could herald a new era for EV manufacturing, offering greater environmental sustainability, enhanced supply chain security, and potentially more cost-effective production for a wide array of electric vehicles.
The ongoing commitment from both industry leaders like YASA and governmental bodies such as the UK’s Department for Business, Innovation, Science and Trade, signifies a collective push towards a more resilient and sustainable future for automotive propulsion. As the global shift to electric mobility accelerates, innovations in core components like electric motors will be pivotal in shaping the industry’s trajectory and delivering on ambitious climate goals. The results of Project Resilience, expected within the next year, are keenly awaited by the automotive and energy sectors worldwide.

Frequently Asked Questions (FAQ)
What is Project Resilience?
Project Resilience is a UK government-funded initiative where YASA is developing two new axial flux motor designs. The primary goal is to reduce or eliminate the need for rare-earth magnets in electric vehicle motors, addressing environmental concerns and supply chain vulnerabilities associated with these critical materials.
Why are rare-earth magnets problematic for EV manufacturers?
Rare-earth magnets, especially heavy rare earths, are vital for high-performance EV motors but their supply chains are geographically concentrated. This exposes manufacturers to risks like export restrictions, price volatility, and potential disruption. Furthermore, their extraction and processing are often carbon-intensive and environmentally taxing.
What are the two development routes YASA is pursuing?
YASA is developing two types of axial flux motor designs: one that is heavy-rare-earth-free, intended for high-performance battery-electric and hybrid vehicles, and another that is entirely rare-earth-free, designed for vehicle applications with different performance, cost, and manufacturing needs.
How does YASA’s modular motor architecture work?
The new designs will use a common YASA stator technology, enabling a modular motor architecture. This means different rotor technologies can be selected and combined with the shared stator based on specific vehicle program requirements.
